On July 30, the China National Center for marine Environment Forecasting said the typhoon is expected to cause "disastrous impacts" to some coastal areas of China, including Shanghai and Zhu san.
The Ministry of Natural Resources also issued a Tsunami warning for the two cities, which could see waves as high as 1m in the early evening.
Meanwhile, Shanghai is facing a dual threat from tropical storms and sunny days.
On July 30, Shanghai evacuated more than 280,000 people, suspended hundreds of flights and ferry services, and imposed road speed limits as Comay (formerly the fourth typhoon in the East Sea) attacked East China with gusts of wind and heavy rain.
Comay made landfall in the port city of Zhoushan, Zhejiang Province in the early morning of July 30, immediately followed by a warning of a Tsunami caused by a strong earthquake off the Russian Far East, raising concerns about larger-than-expected storms along the Chinese coast.
Authorities said at least 640 flights could be canceled at Shanghai's two main airports on July 30, including 410 flights at the East gate and 230 flights at Hong Kieu.
Local media reported that all ferry services in Shanghai have been canceled since the morning of July 30, and drivers are advised to drive below 60 km/h on the expressway.
Shanghai's Disneyland and Legoland Parks remain open. However, some games and performances at Legoland will be suspended due to weather conditions.
Airports in neighboring cities of Nian Ba, Wenzhou and Hangzhou have also seen flights canceled and diverted. As of the morning of July 30, more than 75% of daily flights in Zhoushan have been canceled.
Some train services in the area have been temporarily suspended, while others operate at limited speeds.
Shanghai is rarely directly affected by strong typhoons, which typically make landfall in southern China.
The most significant typhoon in recent years to hit Shanghai directly is Bebinca in 2024, the strongest tropical storm to hit the Chinese financial capital since00.
Comay made landfall in Zhoushan in the early morning of July 30 with maximum sustained winds of 83 km/h near the center. Forecasters expect Comay to make landfall again near Shanghai late on July 30.
The storm coincided with a Tsunami caused by an 8.7 term richter earthquake off the coast of Russia's Kamchatka Peninsula on July 30, about 4,000km from Shanghai.
A 3m high sunny warning has been issued along Japan's Pacific coast due to the Tsunami.
Earthquake-caused sunsones are capable of traveling thousands of kilometers across vast oceans without losing power.
